Article trading process

ABSTRACT

Articles such as compact discs are traded among a plurality of members who are registered in a common community. Each member has an account including a trading credit balance and a mailing address. A user interface is provided that allows a member to enter articles that the member owns and is willing to trade and articles that the member wants to own. The user interface also receives article trading instruction messages. An administration computer hosts the plurality of members and facilitates article trades among the members. The administration computer identifies matches between owned and wanted articles. For each identified match, an article trading instruction message is sent to the article owner requesting that the article owner mail the owned article to the mailing address of the member who wants to own the article. If the member sends the article, a trading credit is posted to the member&#39;s account and a trading debit and a monetary charge is posted to the member&#39;s account who will be receiving the article. Each traded article has the same trading credit. A priority algorithm is used to select the member who will receive the article if there is more than one member who wants an article that another member owns and is willing to trade. The priority algorithm is based in part on a member score that is a function of the relative value of the articles that a member owns and sends to another member compared to the relative value of the articles that the member wants and receives from another member, the relative value of the articles being determined by a demand for the article compared to a supply for the article among the members. A portion of the monetary charge is placed in a pool for distribution to the content creator of the article.

CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application No. 60/779,759 filed Mar. 6, 2006.

BACKGROUND OF THE INVENTION

Online trading sites allow potential buyers and sellers of goods and services to locate each other. One popular type of online trading sites allow persons who have used goods to offer the goods to others and receive some form of value for the goods. Certain online trading sites that are designed for used goods allow for barter-type transactions. Although many barter-type trading sites exist, there is still a need for improved sites.

BRIEF SUMMARY OF THE INVENTION

In one preferred embodiment of the present invention, articles are traded among a plurality of members who are registered in a common community. Each member has an account including a trading credit balance and a mailing address. A user interface is provided that allows a member to enter articles that the member owns and is willing to trade and articles that the member wants to own. The user interface also receives article trading instruction messages. An administration computer hosts the plurality of members and facilitates article trades among the members. The administration computer identifies matches between owned and wanted articles. For each identified match, an article trading instruction message is sent to the article owner requesting that the article owner mail the owned article to the mailing address of the member who wants to own the article. If the member sends the article, a trading credit is posted to the member's account and a trading debit and a monetary charge is posted to the member's account who will be receiving the article. Each traded article has the same trading credit.

DETAILED DESCRIPTION OF THE INVENTION

Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention.

The present invention is described in the context of a preferred embodiment of a web-based software application commercialized on the World Wide Web at lala.com, which is a music trading site. Lala.com is a service of la la media, inc., Palo Alto, Calif. However, the scope of the present invention is not limited to this particular implementation of the invention. The present invention is described in the context of a plurality of distributed computers, all of which are linked together by an electronic network, such as the Internet. The computers may be any type of computing device that allows a user to interact with a web site via a web browser. For example, the computers may be personal computers (PC) that run a Microsoft Windows® operating system. The computers may also be handheld, wireless devices.

I. DEFINITIONS

The following definitions are provided to promote understanding of the present invention.

article: an article is an item or commodity. An article can be in “tangible” form or can initially be in “intangible” form, but can be put in tangible form when traded. For example, a member of the community may own an article such as a music recording, video presentation, or printed material such as a book in electronic form only, along with rights to copy the article into a tangible form such as onto a portable electronic medium (e.g., CD, DVD) or paper, as well as the rights to transfer the article to another person. This type of intangible article can be traded in its tangible form.

own: ownership as used herein includes full ownership rights conveyed in accordance with the “first sale doctrine” (discussed below). Ownership also includes ownership of a limited use license (e.g., based on time, playback amounts). Accordingly, members can trade articles that convey only the remaining license rights, wherein the members would indicate the remaining license rights in their list.

album: one or more audio recordings issued together, originally released on 12-inch phonograph records (usually with record covers) and later on cassette audio tape and now usually on compact disc. Albums and compact discs (CDs) or “discs” are used interchangeably throughout the disclosure.

administration computer: a computer or processor that administers the trading platform for the members. The administration computer may be a single computer or a network of computers, such as a server or network of servers.

II. TRADING PROCESS

A. Overview of Trading Process

In one preferred embodiment of the present invention, articles are traded among a plurality of members registered in a common community using a computer-implemented process. Each member has an account that includes a trading credit balance and a mailing address. A user-interface allows a member to enter articles that the member owns and is willing to trade and articles that the member wants to own. The user interface also allows the member to receive article trading instruction messages. An electronic network, such as the Internet, is used to communicate between the user interface and an administration computer that is associated with the community. The administration computer hosts the plurality of members and facilitates article trades among the members via the electronic network. The administration computer identifies matches between owned and wanted articles. For each identified match, the administration computer sends an article trading instruction message to the article owner notifying the article owner that the article is requested. If the article owner agrees to send the article, the article owner is provided with the mailing address of the member who wants to own the article. The administration computer then posts a trading credit to the member's account who agreed to send the article and posts a trading debit and a monetary charge (interchangeably referred to herein as a “trading fee”) to the member's account who will be receiving the article. The monetary charge is preferably posted only upon receipt by the administration computer of an article trading confirmation message from the member who was sent the article indicating that the member received the article in acceptable condition, or after a predetermined time has passed since the article was shipped. Thus, if the member does not provide an article trading confirmation message after the predetermined period of time (which is a time period greater than an expected shipping receipt date), it is presumed that the article was received in acceptable condition. If the member who was sent the article indicates that the article was received in unacceptable condition, the administration computer posts a trading credit and cancels the monetary charge to the member who was sent the article. During the estimated “in-transit” time period of the article, the trading credit and monetary charge is only temporarily posted and is not made final. Thus, the trading debit is not made final, and no monetary charge is officially made until the receipt confirmation stage. For example, if payment is made via a credit card, no credit card charge is submitted until receipt confirmation.

Each trading credit entitles a particular member to receive one article from any other member who is not necessarily a member that the particular member sent articles to. That is, the article trades are one-way article trades and members do not trade directly with each other.

In one preferred embodiment of the present invention, each traded article has the same trading credit. In one scheme, traded articles are all of the same type (e.g., audio compact discs (CDs), such as CDs containing musical recordings; audio recordings on other forms of computer-readable media). Even if all articles are of the same type, all articles do not have the same marketplace value. For example, popular, recently released CDs are inherently more valuable than older and/or less popular CDs. In the embodiment wherein each traded article has the same trading credit, members who own more valuable articles and agree to ship them to other members are preferably rewarded via a priority scheme that entitles the member to a higher priority for receiving articles that they want, as opposed to being rewarded with differing amounts of trading credits. More specifically, the administration computer uses a priority algorithm to select the member who will receive the article if there is more than one member who wants an article that another member owns and is willing to trade. The priority algorithm is described in more detail below, but can be generically described as being based upon one or more supply/demand indicators and trading behaviors. In a large, robust community of members, having a lower priority rating does not necessarily mean that the member will never receive requested articles. It merely means that the member may have to wait longer to receive the article. In some instances, however, a member might never receive a requested article that is particularly popular.

In alternative embodiments of the present invention, the articles may be of different types, such as books, CDs, and digital video discs (DVDs). That is, one type of article may be traded for another type of article.

To minimize abuses and promote fairness in the community, members are inhibited from trading under certain conditions. One condition is when their trading credit balance is less than a predetermined amount, thereby preventing members who have a trading credit balance that is less than the predetermined amount (e.g., zero) from receiving any articles wanted by the members. Another condition is when a member has more than a predetermined amount of trades that have been initiated but not yet completed (“in-transit” trades). The administration computer optionally assigns risk assessment scores to members based on their trading activity, as described in more detail below. The risk assessment scores can be used to set the trading credit balance number and the in-transit limit so that different members can have different trading credit balance numbers and in-transit limits. For example, members who have a steady, high level of trading activity may be allowed to have a very large number of in-transit articles and may also be allowed to run a negative trading credit balance.

In one preferred embodiment, members have the option to indicate on their list of owned articles whether they are agreeable to trade it. In this embodiment, members are not required to send an article after being requested to do so by the administration computer. The member can either respond to the administration computer with a message to that effect, or if no response is received from the member within a predetermined time period, the administration computer can presume that the member does not wish to send the article. That is, members are never required to trade. They are only notified of an opportunity to trade. Over time, most members who repeatedly receive requests for articles that they do not wish to send but have not marked as such, will eventually either change the article designation to “owned, not willing to trade” (“keep it” setting) or will send the article in response to a subsequent request. The “keep it” setting suppreses notifications of trading opportunities. If the “keep it” option is not set, the article owner will continue to see the notification of trading opportunity unless the administration computer deletes it due to fulfillment by another member, but the article owner does not have to act on the trading opportunity.

In another preferred embodiment, the user interface further allows a member to transfer a portion of their trading credit balance to another member.

Method for Filtering Tradeable Demand

The administration computer generates a list of tradeable requested discs and stores them in the Demand table (FIG. 4) by processing in real-time all the discs in members' want lists and stored in the Want list table (FIG. 11). The goal of such processing is to remove discs which meet the following conditions:

-   -   1. All discs requested by members with a suspended account flag         in the User Table (FIG. 6).     -   2. All discs requested by members with a canceled account flag         in the User Table (FIG. 6).     -   3. All discs requested by members with a trade suspended flag in         the User Table (FIG. 6). Trade suspended flags can be assigned         to a member by administrators due to fraud concerns or by the         billing system due to failed payment.     -   4. All discs requested by members with an invalid or missing         credit card flag in the User Table (FIG. 6).     -   5. All discs requested by members with a vacation mode flag in         the User Table (FIG. 6) indicating they do not wish to receive         discs at this time.     -   6. All discs requested by members with a trade balance less than         their min balance.         -   a) The member's trade credit balance is calculated from the             User Score Table (FIG. 9) as follows: Shipping (total discs             shipped) minus Receiving (discs sent to customer via trade)             plus Bad_Receive (discs received in bad condition or never             received);         -   b) The min_balance is obtained from the Trade Limits Table             (FIG. 10) based on their assigned limitid. The limitid is             assigned to the member based on their trading history (see             Risk Assessment Score).             This method is invoked any time on the following conditions             occurs thereby yielding real-time tradeable demand in the             system:     -   1. Member's suspended flag is removed;     -   2. Member's canceled flag is removed;     -   3. Member's trade suspended flag is removed;     -   4. Member's credit card is successfully updated;     -   5. Member's vacation flag is removed;     -   6. Member's trade balance changes due to trade activity         including Shipping a disc via trade, Receiving a disc via trade,         Confirming a disc received via trade, or when a previously         Shipped disc via trade by the member is confirmed by the         receiving member;     -   7. Member's Trade Limits change due to a change in the limitid         assignment

Method for Filtering Tradeable Inventory

The administration computer generates a list of tradeable owned discs and stores them in the Inventory table (FIG. 5) by processing in real-time all the discs in members' have lists which are stored in the Have List table (FIG. 12). The goal of such processing is to remove discs which meet the following conditions

-   -   1. All discs owned by members with a suspended account flag in         the User Table (FIG. 6).     -   2. All discs owned by members with a canceled account flag in         the User Table (FIG. 6).     -   3. All discs owned by members with a trade suspended flag in the         User Table (FIG. 6). Trade suspended flags can be assigned to a         member by administrators due to fraud concerns or by the billing         system due to failed payment.     -   4. All discs owned by members with an invalid or missing credit         card flag in the User Table (FIG. 6).     -   5. All discs owned by members with a vacation mode flag in the         User Table (FIG. 6) indicating they do not wish to receive discs         at this time.     -   6. All discs with a keep it flag in the status field in the Have         List Table (FIG. 12)     -   7. All discs owned by members with a trade balance greater than         their max_balance value allowed.         -   a. The member's trade credit balance is calculated from the             User Score Table (FIG. 9) as follows: Shipping (total discs             shipped) minus Receiving (discs sent to customer via trade)             plus Bad_Receive (discs received in bad condition or never             received);         -   b. The max_balance is obtained from the Trade Limits Table             (FIG. 10) based on their assigned limitid. The limitid is             assigned to the member based on their trading history (see             Risk Score Algorithm).     -   8. All discs owned by members with an Intransit value greater         than their max_outbound value allowed.         -   a. The member's Intransit value is calculated from the User             Score Table (FIG. 9) as follows: Shipping (total discs             shipped) minus Good_Ship (discs sent to customer via trade             and confirmed as received in good condition) minus Bad_Ship             (discs sent to customer via trade and confirmed as received             in bad condition or never received);         -   b. The max_outbound value is obtained from the Trade Limits             Table (FIG. 10) based on their assigned limitid. The limitid             is assigned to the member based on their trading history             (see Risk Score Algorithm).             This method is invoked any time on the following conditions             occurs thereby yielding real-time tradeable demand in the             system:     -   1. Member's suspended flag is removed;     -   2. Member's canceled flag is removed;     -   3. Member's trade suspended flag is removed;     -   4. Member's credit card is successfully updated;     -   5. Member's vacation flag is removed;     -   6. Member changes the keep it flag associated with a disc;     -   7. Member's trade balance changes due to trade activity         including Shipping a disc via trade, Receiving a disc via trade,         Confirming a disc received via trade, or when a previously         Shipped disc via trade by the member is confirmed by the         receiving member;     -   8. Member's Trade Limits change due to a change in their limitid         assignment

Method for Notifying Owners of Matched, Tradeable Discs

The administration computer generates notifications to the owners of tradeable discs in the Inventory Table (FIG. 5) which are matched with tradeable discs in the Demand Table (FIG. 4) as follows:

-   -   1. Administration computer generates a list of distinct disc ids         from the Demand Table (FIG. 4). Each disc id is identified as a         cover art only or cover art optional based on the following:         -   a. If at least one of the discs for a given disc id has a             cover art optional attribute in the status field in the             Demand table, the disc id is identified as cover art             optional.         -   b. If all the discs for a given disc id have a cover art             required attribute in the status field in the Demand table,             the disc id is identified as cover art required.     -   2. When a member logs in or checks their Have List, the         administration computer matches:         -   a. The list of distinct disc ids in the Demand Table             identified as cover art optional is compared with the             member's disc ids in the Inventory Table (FIG. 5). Any disc             matched is flagged to the member as a tradeable disc and             listed under their requested discs list.         -   b. The list of distinct disc ids in the Demand Table             identified as covert art only is compared with the member's             disc ids in the Inventory Table (FIG. 5) which have the             cover art available attribute in the status field. Any disc             matched is flagged to the member as a tradeable disc and             listed under their requested discs list.     -   3. Periodically (e.g., every 8 hours), the administrator         computer executes a batch to identify matches between discs in         the Demand Table and discs in the Inventory Table and emails the         owners of matched discs. The batch accounts for cover art         preferences and availability as specified in 2 above.

Method for Posting Executed Trades

Once the receiver is selected for a trade by means of the priority algorithm, the administrator computer will perform the following to post the trade:

-   -   1. Provide the Owner of the disc with the Receiver's current         mailing address from the Address Table (FIG. 7)     -   2. Send an electronic message to the Owner of the disc with         confirmation of the trade using the contact information in the         User Table (FIG. 6)     -   3. Send an electronic message to the Receiver of the disc with         confirmation of the trade using the contact information in the         User Table (FIG. 6)     -   4. Create a row in the Shipping Table (FIG. 13) for the executed         trade with a pending status until confirmed by the receiver.     -   5. Update the shipper trade credit balance by incrementing the         shipping field by one in the User Score Table (FIG. 9)     -   6. Update the receiver trade credit balance by incrementing the         receiving field by one in the User Score Table (FIG. 9)     -   7. Deletes the entry for the shipper's disc from the Have List         Table (FIG. 12) and the Inventory Table (FIG. 5.)     -   8. Deletes the entry for the receiver's disc from the Want List         Table (FIG. 11) and the Demand Table (FIG. 4)

Method for Handling Trade Confirmation

The receiver of a disc via trade is presented with a trade confirmation page to report the outcome of the trade. The administrator computer updates the shipper's and receiver's trade credit balance based on reports submitted by the receiver of the disc. The trade credit balance is updated by making the following changes in the User Score Table upon confirmation by the receiver:

-   -   1. If the receiver reports that disc was received in good         condition,         -   a. The trade credit balance for the receiver is updated by             incrementing by one the good_receiver value for the receiver             in the User Score Table     -   b. The trade credit balance for the shipper is updated by         incrementing by one the good_ship value for the shipper in the         User Score Table         -   c. Updates the receive condition for the trade in the             Shipping Table to create a billable event for the receiver         -   d. Adds a row for the disc for the receiver in the Have List             Table (FIG. 12)     -   2. If the receiver reports that the disc was never received or         was received in bad condition or was the wrong disc received         -   a. The trade credit balance for the receiver is updated by             incrementing by one the bad_receiver value for the receiver             in the User Score Table         -   b. The trade credit balance for the shipper is updated by             incrementing by one the bad_ship value for the shipper in             the User Score Table         -   c. Adds a row for the disc for the receiver in the Want List             Table (FIG. 11) so the disc can be received via another             trade     -   3. If the receiver does not submit a report within x days after         the trade was initiated (e.g., 14 days), the administrator         computer will contact the receiver electronically to request a         confirmation.     -   4. If the receiver does not submit a report within y days after         the trade was initiated (e.g., 21 days), the administrator         computer automatically confirm the trade as received in good         condition and,         -   a. The trade credit balance for the receiver is updated by             incrementing by one the good_receiver value for the receiver             in the User Score Table         -   b. The trade credit balance for the shipper is updated by             incrementing by one the good_ship value for the shipper in             the User Score Table         -   c. Updates the receive condition for the trade in the             Shipping Table to create a billable event for the receiver         -   d. Adds a row for the disc for the receiver in the Have List             Table (FIG. 12)

III. PRIORITY SCHEMES

A. Overview of Priority Schemes

In one preferred embodiment of the present invention, each article has a quality score that is a function of the current demand for the article to the current supply of the article among the members. Each member has an account that includes a trading credit balance that reflects the difference between the number of articles that the member previously owned and traded to other members and the number of articles that were sent to the member by other members. Each account also includes a quality balance score. The quality balance score is the sum of the articles previously sent by the member that had a quality score greater than the quality score of the article that the member currently wants to receive minus the sum of the articles previously received by the member that had a quality score greater than the quality score of the article that the member wants to receive. In this embodiment, the priority algorithm referred to above uses at least the trading credit balance and the quality balance score as factors in the algorithm to select the member who will receive the article.

In an alternative embodiment of a priority scheme, the members receive an overall priority that is not tied to a specific wanted article, and the overall priority is used as a factor in deciding the priority for receiving the specific wanted article. The member's priority is still calculated based upon supply/demand factors. For example, a supply/demand score for each article that a member ships (at the time that the member ships it) may be compared to an average supply/demand score for all articles (at the time that the member ships it) to obtain a supply/demand score ratio, and a running average of the supply/demand score ratio may be used as a factor in calculating the priority.

Other factors that may be used in the priority algorithm include a distance between mailing addresses of identified matching members and the amount of time since a member last received an article. For example, it is preferable to ship articles to members who are close to each other so as to reduce delivery time and thereby increase user satisfaction with the trading process. Likewise, it is preferable to give priority to members who have the longest time span since the previous delivery. Different weightings may be assigned to each of the factors discussed above.

Various combinations and permutations of these priority schemes may be used. The supply/demand calculations may be based upon supply/demand among the members or a marketplace supply/demand calculation. One advantage of the priority schemes described herein is that they simplify the trading process by allowing for one-to-one trading, while still rewarding members who trade popular articles with a valuable benefit, namely, increased speed and likelihood of receiving wanted articles from other members.

B. Detailed Disclosure of Priority Schemes

Priority Algorithm and Quality Score and Risk Assessment Score If the owner of a disc agrees to ship a disc with two or more members requesting the disc in the Demand Table (FIG. 4), the administrator computer selects a member to receive the disc as follows: 1. A priority score for the disc in question is computed for each member requesting the CD as follows: $\begin{matrix} {{{Priority}\quad{Score}\quad{for}\quad{{Member}(i)}\quad{for}\quad{{Disc}(j)}} =} \\ \begin{bmatrix} {{Predetermined}\quad{WeighFactor} \times} \\ {{Trading}\quad{Credit}\quad{Balance}\quad{for}\quad{{Member}(i)}} \end{bmatrix} \\ \begin{bmatrix} {{Predetermined}\quad{WeighFactor} \times} \\ {{Quality}\quad{Balance}\quad{{Score}(j)}\quad{for}\quad{{Member}(i)}} \end{bmatrix} \\ \begin{bmatrix} {{Predetermined}\quad{WeighFactor} \times} \\ {{Days}\quad{Since}\quad{Last}\quad{receive}\quad{score}\quad{for}\quad{{Member}(i)}} \end{bmatrix} \\ \begin{bmatrix} {{Predetermined}\quad{WeighFactor} \times} \\ {{Distance}\quad{in}\quad{miles}\quad{between}\quad{{Member}(i)}\quad{mailing}\quad{address}\quad{and}} \\ {{the}\quad{owner}\quad{of}\quad{{disc}(j)}\quad{mailing}\quad{address}} \end{bmatrix} \end{matrix}$ 2. Selecting the member with the highest priority score to receive the disc in question. Trading Credit Balance is calculated from the User Score Table (FIG. 9) as follows: Shipping (total discs shipped by member via trade) minus Receiving (total discs received by member via trade)+Bad_Receive (discs received in bad condition or never received); Quality Balance Score(j) is equal to: [Σ discs shipped by member(i) with a Quality Score at time of trade>=Quality Score disco)]minus [Σ discs received in good condition by member(i) with Quality Score at time of trade>=Quality Score for disc(j)]

-   -   Where Quality Score for disc(x) is a function of the total         demand in the Demand Table for disc x and the total inventory in         the Inventory Table for disc x.     -   As example, the Function to determine the Quality Score for         disc(x) could be computed as:         -   If Total Inventory for disc(x)>=1,             Quality Score for disc(x)=[Total Demand for disc(x)]²÷[Total             Inventory for disc(x)]         -   Else,             Quality Score for disc(x)=[Total Demand for disc(x)]             The Risk Assessment Score

The Risk Assessment Score is computed as a function of the number of trades executed by the member and the ratio of good trades to total trades. The User Score Table is used to compute the Risk Assessment Score.

For example, the Risk Assessment Score can be derived from User Score Table as follows: [WeightFactor(i)]×[Good_Ship]+[WeightFactor(j)]×[(Good_Ship)÷(Good_Ship+Bad_Ship)] For each Risk Assessment Score or range of scores, the administration computer assigns members to a unique LimitID in the Trade Limits Table (FIG. 10). Each LimitID has been pre-assigned with certain trading limit values that correspond to assessed levels of risk for trade. For example, FIG. 26 shows a table that can be used to interpret the use of Risk Assessment Scores, LimitIDs, and Trading Limits.

IV. ARTIST CONTRIBUTION FOR TRADED ARTICLES

A. Overview of Artist Contribution for Traded Articles

The first-sale doctrine is a limitation upon copyright that is codified in the Copyright Act of 1976, 17 U.S.C. § 109. The doctrine of first sale allows the purchaser to transfer (i.e., sell or give away) a particular, lawfully made copy of the protected work without permission once it has been obtained. That means the distribution rights of a copyright holder end on that particular copy once the copy is sold. Accordingly, when used articles, such as musical recordings on albums or CDs, books and the like, are resold, neither the artists who created the content of the articles, nor any entities that marketed, manufactured or distributed the articles, receive any additional revenue as a result of the sale of the used articles. Used articles usually sell for less than new articles. A certain percentage of consumers who are interested in the article will purchase a used article instead of a new article so as to save money, thereby reducing revenue earned by the artists and their marketing partners. The artists and their marketing partners typically cannot compensate for the used sales by raising the original price of the articles because the marketplace typically sets the price for new articles. Furthermore, the marketability of used articles has increased dramatically since content on digital media is smaller and more compact, and less likely to degrade than recordable media forms such as albums (vinyl) and cassette tape that were previously used.

One ramification of this situation is that so-called “struggling artists” have to struggle even harder to earn revenue. Another ramification is that some content creators and their marketing partners are starting to develop complicated schemes to restrict or prevent reuse of content by anybody other than the original purchasers. These schemes are generally not well-received by consumers who believe that they should be able to resell used articles. The impacts on the struggling artists and the developing conflicts between content creators and their marketing partners and consumers could potentially be reduced if the content creators and their marketing partners could receive additional revenue from trades and sales of their used articles.

In one preferred embodiment of the present invention, one or more pools of funds are created for distribution to a plurality of content creators who produce content that is sold to individuals in the form of an article. The trading scheme described above is used as the platform for the creation of the pool(s) of funds. In one scheme, the administration computer automatically allocates a portion of each trading fee to be placed in the pool(s) of funds for distribution to the plurality of content creators. Preferably, the administration computer records data for each trade, including the content creator associated with each traded article, and then allocates the pool of funds to individual content creators in proportion to the trades related to articles produced by the respective content creators. However, other types of allocation schemes are within the scope of the present invention. A user interface may be provided that allows content creators to register with the administration computer and set up content creator accounts to allow funds to be transferred from the pool of funds to respective content creator accounts. The portion of the trading fee may be a predetermined fixed amount or a predetermined percentage of each trading fee, such as about 20% of the trading fee.

In an alternative embodiment, one or more of the pools of funds are distributed to a plurality of entities that market, manufacture or distribute content that is sold to individuals in the form of an article, and the administration computer automatically allocates a portion of each trading fee to be placed in the pool(s) for distribution to the plurality of entities. That is, content creators and/or their marketing partners can be compensated for used sales of their articles.

The amount of funds placed in the pool(s) does not necessarily have to be amount associated with a trading fee. Instead, the amount may be placed in the pool(s) for every trade, regardless of whether or not a trading fee is incurred. The amount may simply be a fixed amount or fixed percentage of some benchmark that is unrelated to any trading fee. This scheme may be used for trading sites that do not charge trading fees or for trading sites that charge trading fees but wish to compensate content creators and/or their marketing partners separate from any trading fee accounting process.

Furthermore, the artist contribution scheme need not be limited to trading sites and is equally applicable to any store (either bricks-and-mortar or internet-based (e.g., website)) that sells or brokers used articles. In this embodiment, an administration computer automatically allocates an amount to be placed in the at least one pool of funds for distribution to the plurality of content creators for each purchase made of a previously sold article. In this embodiment, the administration computer primarily functions to maintain inventory of articles for sale, instead of, or in addition to, articles for trade, but shares the capabilities described above for tracking funds to be distributed to content creators and their marketing partners.

V. COMMUNITY SHARING OF MEMBER INTERESTS AND SEARCHING METHODOLOGIES FOR FACILITATING THE SHARING OF MEMBER INTERESTS

A. Overview of Sharing of Member Interests and Searching Methodologies for Facilitating the Sharing of Member Interests

As described above, one preferred embodiment of the present invention provides a community of members who can trade music recordings. To facilitate a sense of community among the members, members are permitted to view music interest data of other members. Music interest data includes music recordings that each member listens to, articles of music recordings (e.g., CDs) that each member owns and is willing to trade, and articles of music recordings (e.g., CDs) that each member wants to own. To encourage sharing of music interest data, the administration computer automatically identifies other members who have similar music interest data with a specific member. The identities of the other members are then automatically displayed to a member when the member logs into the community. For example, the identities of the eight most similar members are shown. The member can then navigate directly to the music interest data of any of the similar members and view the music recordings that the other member listens to, owns and wants to own. By viewing such data, members may learn of music recordings that the member may not have otherwise considered owning. In turn, this may encourage the member to add certain music recordings to the member's list of wanted music recordings. The global effect of this sharing process is to increase the overall level of trading activity among the members and strengthen member affinity to the community.

A similar experience may occur as a result of a search process by a member. Members are provided with a search function that allows the member to search for music recordings by keyword, or by artist, album, song, member or the like. The search is processed by a search engine and results are returned and displayed to the member. In addition to the search results, for certain types of searches, the member is shown the identities of other members who have similar music interest data as the search request. Some examples are as follows:

1. Search input is “Jay Farrar.” Eight member identities are shown who have a similar interest in Jay Farrar, as determined from one or more of the music interest data.

2. Search input is “rhythm.” Eight member identities are shown who have a similar interest in rhythm music, as determined from one or more of the music interest data.

In one preferred embodiment of the present invention, identities of members in a common community of registered members who have similar interests in music recordings are displayed to other members. The members can trade articles containing music recordings with each other. An administration computer maintains music interest data of members including music recordings that each member listens to, articles containing music recordings that each member owns, and articles containing music recordings that each member wants to own. The administration computer applies a distance function to at least some of the music interest data to determine how similar the music interests of a member is to the music interests of other members. The identities of a predetermined number of other members who are determined to have similar music interests as the member are displayed to the member via a user interface. The member may then navigate to a display of at least some of another member's music interests by selecting the member's identity displayed on the user interface. In one scheme, all of the music interest data (i.e., listened to music, owns and wants) is used as factors in the distance function and all of another member's music interest data is displayed.

In another preferred embodiment, the user interface further allows members to enter searches for articles containing music recordings or properties of articles containing music recordings, and the determination of similar music interests is made using the search entry.

In another preferred embodiment of the present invention, identities of members are displayed who have similar sets of articles as other members in a common community of registered members. The common community allows members to list articles that members own and articles that members want to own and to trade articles among each other. An administration computer maintains data of articles that each member owns and articles that each member wants to own. The administration computer uses at least some of the article data to determine for a member how similar the other members' sets of articles are to the set of articles owned by the member. In one preferred scheme, a distance function is used for the similarity determination. The identities of a predetermined number of other members who are determined to have similar sets of articles as the member are displayed to a particular member. The member can then navigate to a display of another member's list of articles by selecting the member's identity, such as via a hyperlink. In one scheme, the identities of the other members are automatically displayed when the member logs into the community. The determination for each member of how similar the other members' sets of articles are to the set of articles owned by the member is made by comparing to only the lists of articles that the members own, or by comparing only the lists of articles that the members want, or by comparing the list of articles that the members own and the list of articles that the members want. Other permutations of comparisons are within the scope of the invention, such as comparing the list of articles that a member wants to the list of articles that other members own and want.

In yet another more generic embodiment, article interest search data, which may be an article or a property of an article, is entered by a member and the similarity determination is made between the entered article interest search data and article interest data of the other members (e.g., articles that each member owns, and articles that each member wants to own). In one scheme, all of the articles are of the same type (e.g., all music recordings on CDs). In another scheme, the articles are of different types (e.g., music recordings on CDs, video recordings on DVDs, books).

Although a specific distance function is described in detail below, the scope of the present invention includes other types of distance functions, as well as other algorithmic techniques for determining the similarity of one set of data to another set of data.

B. Detailed Disclosure of Sharing of Member Interests and Searching Methodologies for Facilitating the Sharing of Member Interests

FIGS. 29-33 are display screens that show how members can share their interests with other members. For example, FIG. 29 shows the resultant display screen for a search of the artist “Jay Farrar.” An upper region of the display screen marked with an oval for convenience includes icons of the identities of eight other members who like Jay Farrar the most, as determined by a similarity algorithm. If desired, a member can then click on one of the identities and view the CD collection of that member, as shown in FIG. 30. Filtering options can be used to narrow down the collection to a subset that matches the filtering options, as shown in FIG. 31.

In one embodiment of the present invention, members can view “listen data” of other members, as shown in FIG. 32. The listen data may be the listen data associated with one of the members located in a search, or the listen data may be the listen data shown for one of the members displayed in FIG. 16 whose collections are similar. In one preferred embodiment of the present invention, the listen data is collected automatically by a software plug-in that keeps track of any music that is played from the user's computer and/or any music that is downloaded into a portable music player, such as an MP3 player or iPod®. FIG. 33 shows a listen plugin download screen display.

Plug-ins for tracking listened to music are well-known, and any known plug-in is suitable to enable this feature. One commercially available plug-in that is suitable for this function is a plugin for the “Yahoo Music Engine,”, commercially available as a free download from Yahoo!® Inc.

FIG. 34 shows a combination flowchart/entity relationship diagram related to the sharing process.

Method for Selecting Members Similar to a User

A plurality of members logs in via the internet and browse discs listed in the Disc Table (FIG. 1).

Members add discs they want to their Want list Table (FIG. 11).

Member adds a number of discs owned to their Have List Table (FIG. 12).

A plurality of members logs in via the internet and installs the Listen Plugin on their PC. As music is played, the Listen Plugin collects listen data and uploads to the Listen Table (FIG. 15). If the member listens on their portable device and then synchronizes with their PC, any listen data reported by the device is also collected and uploaded to the Listen Table.

User X subsequently logs in via the internet and clicks on their personal home page. The administration computer then invokes a method for retrieving a list of other members similar to User X.

The administration computer method relies on a Similarity Algorithm to determine a list of similar members to User X. The Similarity Algorithm is computed by using various distance functions between users of the community.

For example, when requested for members similar to a member A, the Similarity Algorithm applies the distance function across all members (A, X) and returns the first N members by distance ascending. The closer the distance to zero, the more similar the members are considered to be. Alternatively, the Similarity Algorithm can also use a “score” where the higher the score between two members the more similar they are.

An embodiment of the Similarity Algorithm can utilize the list of discs owned by user X to find similar members (It is important to note that the Similarity Algorithm could also utilize other articles such as the list of discs requested, or a list of music listened to):

-   -   1. The first distance function is the cardinal of the         intersection between the discs owned by User X and the rest of         the members in the community. This function is computed as         follows:         -   a. The administration computer utilizes User X unique             identifiers, the userkey and the md5key from the User Table             (FIG. 6), to retrieve the current list of discs owned by             User X from the Have List Table.         -   b. The administration computer then utilizes the list to             compute a histogram from the Have List Table which yields             one row per user in the Have List Table and the number of             discs owned by each user which are also owned by User X.         -   c. The distance between User X and any of the members (e.g.,             User Y) is computed as follows:             Distance(X,Y)=|A|−|AinterB|,         -   where A is the total number of discs owned by User X,         -   B is the total number of discs owned by User Y, and         -   |A inter B| is the total number of discs owned by User Y             also in List Y, obtained from the histogram in step (b).     -   2. A second distance function can also be used to address a         drawback with the cardinal distance function where members with         large collections of discs will be similar to everyone. The         second distance function alleviates the issue by having the         distance be the ratio of the size of the intersection by the         average size of the each users owned disc list;         -   Distance(A,B)=(|A|−|A inter B|)÷(|A|+|B|)/2; where A is the             total number of discs owned by User X, B is the total number             of discs owned by User B and |A inter B| is the total number             of discs owned by User B and also in A,     -   3. A third distance is computed by computing the distance         between the probability distribution of the users' listen list         against a genre. The Kullback Leibler Distance (KL) is defined         by:         Σ(p*log(p/q)) for each genre         -   For example, if comparing user A and User B with the             following probabilities of listen data in each genre:             -   User A: {genre1: 0.1, genre2: 0.4, genre3: 0.5}             -   User B: {genre1: 0.2, genre2: 0.3, genre3: 0, genre4:                 0.5}                 The KL                 value=0.1*log(0.1/0.2)+0.4*log(0.4/0.3)+0.5*log(0.5/0)+0*log(0/0.5)     -   4. The Algorithm has the ability to use the most appropriate         distance functions in a given context. The first two functions         allow for very fine grain comparisons whereas the third provides         more robust coarse grain comparisons.     -   5. The Algorithm can also take advantage of a user's most recent         query and fine-tune the set of similar members based upon that         additional information. When a member A performs a search for a         certain artist S, the distance functions can be modified to         increase the member's weight in that artist. In the first two         distance functions, this may consist of just “adding” all or a         subset of the discs by that artist to the member's collection         (for the time of the similarity computation); Similarly the         third distance function can be tuned by increasing the         probability of the artist's genre in the member's listen table.

VI. PROCESS TO SUPPLY PACKAGING/SHIPPING MATERIALS

A. Overview of Process to Supply Packaging/Shipping Materials

In one preferred embodiment of the present invention, members are provided with postage-paid mailing envelopes and article cases so as to allow the members to mail articles that the members own to other members of the common community as part of the article trading process. The envelopes have no addressee printed thereon. The members are instructed by the administration computer as to who the addressee should be when a match is located. Although no postage for trades is paid when mailing envelopes and cases to members, there is still a cost to the administrating entity in purchasing, printing and mailing the envelopes and cases to the members. Accordingly, it is desirable to control the circulation of envelopes and cases so that the supply and demand of envelopes and cases is kept at a level where all members have a ready supply of envelopes and cases so that articles can be shipped immediately upon a match being identified, without incurring unnecessary costs by oversupplying such materials to the members.

To achieve this goal, the administration computer automatically outputs shipment orders to mail the envelopes to the members and the administration computer includes business logic rules for determining when to output the shipment order, the quantity of envelopes to ship, and whether to include cases in the shipment order. In one scheme, the administration computer sends an electronic message to a member upon the output of a shipment order related to the member requesting that the member respond to the electronic message by indicating whether the member wants an additional quantity of envelopes. In another scheme, the administration computer automatically mails the envelopes to the member based on the outputted shipment order. Predictive rules based upon at least a member's trading behavior may be used to determine when to output the shipment orders.

To further minimize unnecessary packaging costs, the user interface may optionally suppress icons and selection options that allow a member to request additional envelopes and cases if the administration computer determines based on member trading histories that the members should not need such materials. Alternatively, the ability to request additional envelopes and cases may be limited to certain quantities based on member trading histories. For new members, an initial shipment of mailers may occur once the user lists a predetermined number of articles (e.g., five CDs) that are available to trade, or if the member submits a credit card number to be maintained on file by the administration computer, regardless of whether any articles are listed as being available to trade.

B. Detailed Disclosure of Process to Supply Packaging/Shipping Materials

FIGS. 35 and 36 are screen displays related to an envelope supplying process. FIG. 35 shows the screen display when a member is prompted to order more envelopes. FIG. 36 shows a screen display that informs the member that they are not eligible to receive more envelopes at the current time.

FIG. 37 shows a combination flowchart/entity relationship diagram related to the envelope supplying process. FIG. 38 shows a flowchart related to the envelope supplying process. FIG. 39 shows an image of a front view of a sample envelope.

One suitable plastic case for use in mailing CDs is a Clam Shell CD Case Model No. S-6765, commercially available from Uline®, Waukegan, Ill. However, any plastic case may be used.

Business logic for the envelope supplying process

The Administration Computer updates the envelope counts and plastic case counts in the Score Table (FIG. 9) every time a trade is initiated or confirmed for a member based on the following rules:

-   -   1. When a member agrees to ship a CD via trade, the member's         envelope count is decreased by one.     -   2. When a member agrees to ship a CD via trade, the member's         plastic case count is decreased by one.     -   3. When a member confirms receiving a CD via trade, the member's         plastic count is increased by one.         The Administration Computer updates the envelope counts and         plastic case counts in the Score Table (FIG. 9) every time a         shipping or confirmed as follows:     -   1. The member's envelope count is increased by the number of         envelopes in the SKU in the shipping order.     -   2. The member's plastic case count is increased by the number of         plastic cases in the SKU in the shipping order.         The Administration Computer determines if a shipping order         should be generated every time a member is part of trade based         on the following rules:     -   1. If member does not have a valid address in the Address Table         (FIG. 7), then the member cannot order any envelopes.     -   2. If member has a valid address in the Address Table (FIG. 7),         but has never been shipped any envelopes, then the         administration processor generates a shipping order for a SKU         with 5 envelopes and 5 plastic cases.     -   3. If a member has 5 or less trades and the member envelope         count is less than 2 and the member has a valid address in the         Address Table (FIG. 7), the member is notified of the option to         order additional envelopes. The member can order a SKU with 5         envelopes and 5 plastic cases.     -   4. If member has more than 5 trades and the member has less than         5 envelopes and member has a valid address in the Address Table         (FIG. 7), then the member is notified of the option to order         additional envelopes. The SKUs available for order are         determined as follows:         -   i. Members with 5 or more trades, can order the following             SKUs:             -   1. 5 envelopes, 0 plastic cases             -   2. 10 envelopes, 0 plastic cases         -   ii. Members with 15 or more trades, can also order the             following SKUs:             -   1. 20 envelopes, 0 plastic cases         -   iii. Members with less than 5 plastic cases on hand, can             also order the following SKUs:             -   1. 5 envelopes, 5 plastic cases             -   2. 10 envelopes, 10 plastic cases

VII. ADDITIONAL EMBODIMENTS OF THE PRESENT INVENTION

Embodiments of the present invention relate to a system and method for on-line searching of information. More particularly, embodiments of the present invention relate to a system and method for a community-based searching and related applications.

On-line search methodologies are well known. However, conventional search methodologies that use cached databases to conduct searches cannot take into consideration information added subsequent to caching, or any real-time information. In addition, convention search methodologies do not take into consideration multi-dimensional inputs that encompass information both provided directly from the user and relevant information from an on-line community to which the user is a member.

An example of an on-line community may include a membership to a community dedicated to the exchange of information about music, and the buying or trading of legally-purchased music. According to the Recording Industry Association of America (RIAA), nearly 30,000 album titles are released each year. With nearly 3 million titles available, large resellers generally only stock about a few thousand titles, or less than 1% of all available music. An on-line community may be formed to exchange information about music, and more specifically, to exchange legally-purchased CDs on fellow community members.

A novel on-line searching methodology for conducting searches based on real-time information, taking into consideration multi-dimensional inputs, and capable of returning multi-dimensional search results relevant to the multi-dimensional inputs.

Embodiments of the method for a community-based search are described in this detailed description of the invention. In this detailed description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding of embodiments of the present invention. One skilled in the art will appreciate, however, that embodiments of the present invention may be practiced without these specific details. Furthermore, one skilled in the art can readily appreciate that the specific sequences in which methods are presented and performed are illustrative and it is contemplated that the sequences can be varied and still remain within the spirit and scope of embodiments of the present invention.

The present invention provides a personalized search, in real-time, that takes into consideration multi-dimensional inputs, some of which are a user's personal preferences and recommendations, and some of which are based upon information of other members of an identified community with similar interests and/or background, and yielding not only search results as requested by the user, but also recommendations that are relevant to the user. The user has the option of identifying a relationship with any particular member in the community. The method then takes the relationship into consideration in conducting the search. The method of the present invention is able to search any database, bring all data into a search engine in real-time, and take into consideration multi-dimensional data feed, or multiple inputs, to produce multi-dimensional outputs. In one embodiment, the database may be created and maintained as part of the search engine. In another embodiment, existing information concerning the user is updated in real-time upon the completion of the search.

As an example, in an on-line community, members can trade-in CDs they have for CDs they want from other members. If a CD is not immediately available for trade, members can buy the CD new or as a digital download at retail prices. Accordingly, the multi-dimensional inputs may include user profile, which may include what CDs the user has to trade and what CDs the user wants, and profiles of other members in the community that are deemed relevant either by the user or the search engine. A user may indicate the relevance to any specific members of the community by indicating certain members as being “friends” or as sharing certain common interests. The search engine may also identify relevant members as part of the search by identifying implicit links, such as behavioral history and past communications. The profiles of these members are then taken into consideration. The search result is therefore tailored specific for the user.

The search engine may be implemented with clustering of fuzzy logic algorithms that are capable of isolate similarities and differences from the community in order to achieve a more personalized search. Depending upon the application, different weightings may be assigned to the various similarities and differences. In other words, the search results may be tailored by adjusting the weightings of different parameters. In addition, the search engine will also take into consideration any anomalies that are inconsistent with the norm. Such anomalies are either eliminated from the search or provided a reduced weighting during the search. Therefore, intentional manipulation of the search results is minimized and eliminated.

In operation, a general search is first performed based upon the general search parameters provided by the user, and then a second search may be conducted, considering the other multi-dimensional parameters, to produce a refined, personalized search result. Specifically, the present invention is directed to a search and recommendation platform. The platform is configured to gather and index data in real-time from a plurality of members to generate search results and recommendations of product or content custom tailored for the individual member. Along with content or product, the platform also makes recommendations of members of the platform that are associated with such product or content. The platform uses a number of inputs and behaviors to compute recommendations for its members, which may include lists of content or product owned or desired by the user members, frequency of use of such content and product, links, explicit and implicit, between individual platform members, levels of inventory and demand for the content and product available on the platform, product or content rating and reviews by members related or unrelated to a specific member, and physical geography.

The method also takes an user's list of desired content or product, their individual list of owned content or product, any known uses by the user of the content or product, and any other known inputs and behaviors for the user to generate either a unique recommendation of new product or content for the user based on comparisons to the plurality of members of the platform, or lists of recommended members whose lists of content or product owned, desired, or used are relevant to the user.

The method of the present invention also assigns a proper weighting to each member in the platform for the purpose of generating better recommendations for a user. The weighting of each member is unique to the user for whom the recommendations are generated and can also vary if the user has made a specific request for a content or product. The calculation of the weighting for members may be based on other members' likeness to the user based on comparisons of their lists of desired content or product, lists of owned content or product, and known uses of content or product, such as an overlap in the have list and want list in the on-line music community example. The weighting may also depend upon the similarities in members' explicit links to other members of the platform. In addition, the weighting may take into consideration a member's knowledge level of the requested content or product. Again in the example of the on-line music community, an artist would be assigned a heavier weighting than a novice.

The weighting may also depend on a member's overall influence as determined by the number of items in their lists of owned content or product that are desired by other members of the platform. Furthermore, the weighting may also take into consideration a member's ability to predict the demand or success of content or product as determined by the timing and number of items placed in the members' list of desired or owned, before such content or product is considered to be in high demand as measured by the number of members that include it in their list of desired content or product or by external market sales, revenue, or distribution data. Lastly, the weighting may be influenced by a member's ability to predict the success of content or product as determined by their use of content or product (e.g., listen to songs) before such content or product is considered to be in high demand as measured by the number of members that include it in their list of desired content or product or by external market sales, revenue, or distribution data. The foregoing examples are for illustrative purposes only. Otherwise factors may also be taken into consideration to influence the weightings of various factors to tailor to the specific applications of the search engine.

The platform of the present invention is also capable to compute member scores and indexes for recommendations of content or product in real-time based on changes to aggregate lists of content or product owned, desired, used, or any other known inputs or behavior by the plurality of members. Correspondingly, the method generates a sorted list of recommended content or product based on the total instances of product or content in the lists of content or product owned or desired by the members, the frequency of use of such content and product, and any other known inputs and behaviors with the proper weight assigned to each member. The weight assigned is unique to the user for whom the recommendations are generated.

The search engine also includes logic means that sorts recommendations based on the overall levels of inventory and demand based on the aggregate lists of content or product owned or desired by the entire plurality of members or a subset of such members. The logic means also filters or sorts an user's recommendations based on product already existing in the user's list of desired content or product or list of owned content or product. The logic means may also be programmed to intentionally introduce recommendations in a random process to increase exposure of content or product by its members;

Therefore, the system of the present invention captures the various members' ‘have lists’, defined as items owned, and ‘want lists’, defined as items desired, captures members frequency and timing of use of the content or product, allows members to find content or products and makes personalized recommendations of related content or product or members of the service, allows members to create explicit associations with other members (e.g., friends list, people to bookmark), and allows its members to browse and compare lists of content or product owned or desired between a member and one or more members in the service.

The system of the present invention is able to integrate the platform to an online service that enables commerce transactions (purchase, subscription, or barter) of the content or products and enables promotion and direct marketing of the content or product to the platform members. The service uses members' lists of desired or owned product to target specific members with varying promotions of content or product and uses member scores to target specific members with promotions of content or product for the purpose of predicting future demand for the product.

The system and method of the present invention allows for trading, or bartering, and keeps track of items that have been bartered and the value given up in the past. In addition, in the bartering or trading, actual money need not be involved as members may optionally choose to keep “credits” for the product traded and such credits may be used to purchase or exchange any desired product from other members in the community. The value of each bartered product is weighted to reflect factors such as past value received and demand. User profiles are also considered to further refine the weightings to optimize business variables.

Accordingly, the present invention provides a system and method for conducting barter transactions between members of a service without using explicit prices or values assigned to the items. Instead, the method utilizes a one for one barter system supported by a matching algorithm that uses as inputs the members' ‘have lists’, defined as items owned available for barter, and ‘want lists’, defined as items desired. The system and method include logic means that allows for ‘many to many’ barter transactions, where individuals may send one of their items to a member, while receiving a desired item from a different member. The system and method also include logic means for computing implicit values for have or want items based on actual or predicted demand for the items by the member community of the service, and for assigning values to the members of the community based on the implicit values of items they have bartered with other members.

In addition, the system and method include logic means for computing a ‘risk’ value for each member such that they are allowed to receive items from their want list from other members first having to give up an item they possess based on the probability that will give up an item of a certain value and/or category in the future. A logic means may also be included for prioritizing the list of members that are possible recipients of an item by examining member behaviors which may include but not limited to implicit values of items bartered, risk values of the members, stated preferences by the members, and implicit preferences computed by the platform. In addition, the system and method of the present invention also includes a logic means that utilizes levels available inventory and demand of the aggregate population to optimize barter transactions between members, and a logic means that weights the members' physical proximity when prioritizing member matches for barter transactions.

In the example of the on-line music community in which legally-purchased music is bartered or traded, the intellectual property rights attached to the music are exhausted after their initial sale. The doctrine of exhaustion allows an owner of a lawfully acquired CD to dispose of the possession of that copy without permission or payment of additional royalties to the copyright holder. As a result, artists were not compensated from the sale of used CDs.

The system and method of the present invention may optionally provide a system to compensate the original owners of intellectual property rights for legal trading of music or other protected works, under which the original owners would receive no compensation.

Accordingly, there is provided a method for distributing compensation directly or indirectly to the original authors, publishers, and any other entities that may benefits from the licensing, sale or use of the original copyrighted or protected content or product based on the resale, trading, or bartering of such copyrighted content or product. Such compensation may include, but are not limited, to royalties, fixed payments, marketing, or promotional agreements, and other forms of monetary or non-monetary compensation. In addition, such compensation may depend on the weighting assigned to factors such as popularity and demand. Any such trading or bartering is tracked by the system of the present invention.

Finally, the system and method of the present invention provides a user interface framework that enables multi-dimensional browsing of members of a platform and content or product associations for those members in the platform. The framework integrates with the platform to enable relationships between the dimensions displayed. For example, the content displayed serves as input to determine members displayed and vice versa. In addition, the framework enables true personalization of the browsing experience for the individual using the framework by integrating with the platform to generate unique content across each dimension based on characteristics of the individual using the framework.

The user interface may be based generally on AJAX (Asynchronous JavaScript And XML) programming, a Web development technique for creating interactive web applications. Small amounts of data are exchanged with the server behind the scenes to make the rendering of the web pages more robust, and increase the Web page's interactivity, speed, and usability.

The user interface framework includes a member browsing element capable of retrieving and displaying lists of members from an underlying platform based on numerous associations with a specific member or with a specific piece of content or product listed in the platform, relaying inputs to the underlying platform for varying the association criteria for retrieving lists of members from the underlying platform, navigating the list of members retrieved if they all do not fit in a single page, and selecting a specific member from the list. In addition, the framework includes a content or product browsing element capable of retrieving and displaying lists of content or product from an underlying platform that are associated with a specific member or with another specific piece of content or product listed in the platform, relaying inputs to the underlying platform for changing, filtering or sorting the list of content or product retrieved and displayed from the underlying platform, navigating the list of content or product retrieved if they all do not fit in a single page, and selecting a specific content or product from the list.

The present invention is also capable of simultaneously displaying the member browsing element and the content or product browsing element in a single page which is originally generated by selecting a specific member. The system uses the member browsing element to retrieve and display lists of members from the underlying platform that are associated with the specific member selected (e.g., friends of the member selected). The system also uses the content or product browsing element to retrieve and display lists of content or product associated in the underlying platform with the specific member selected, and contains user interface (UI) elements for changing the association criteria for retrieving the list of members displayed in the member browsing element. For example, the individual may request to view members explicitly linked to another member or view members that are implicitly considered as similar by the platform. The system further includes UI elements for changing, filtering, or sorting the list of content or product associated with the specific member that is retrieved and displayed. As part of the retrieval, the user interface passes unique values that identify the individual using the framework. In this manner, the platform can return a personalized list of content or product based on the individual enabling comparisons, recommendations, sorting, and other operations on the content or product listed using the individual's preferences in the platform.

The present invention provides a system for simultaneously displaying the member browsing element and the content or product browsing element in a single page generated by selecting a specific content or product item in the platform. The system uses the content or product browsing element to retrieve and display lists of content or product associated in the underlying platform with the specific content or product item selected. The system also uses the member browsing element to retrieve and display lists of members from the underlying platform that are associated with the specific content or product item selected. UI elements are incorporated for changing, filtering, or sorting the list of content or product associated. As part of the retrieval, the user interface passes unique values that identify the individual using the framework. In this manner, the platform can return a personalized list of content or product based on the individual; enabling comparisons, recommendations, sorting and other operations on the content or product listed using the individual's preferences in the platform.

In accordance with an embodiment of the present invention, instructions adapted to be executed by a processor to perform a method are stored on a computer-readable medium. The computer-readable medium can be a device that stores digital information. For example, a computer-readable medium includes a read-only memory (e.g., a Compact Disc-ROM (“CD-ROM”) as is known in the art for storing software. The computer-readable medium can be accessed by a processor suitable for executing instructions adapted to be executed. The terms “instructions configured to be executed” and “instructions to be executed” are meant to encompass any instructions that are ready to be executed in their present form (e.g., machine code) by a processor, or require further manipulation (e.g., compilation, decryption, or provided with an access code, etc.) to be ready to be executed by a processor.

To summarize, the following embodiments of the present invention are provided:

1. A platform configured to gather and index data in real-time from a plurality of members to generate search results and recommendations of product or content custom tailored for the individual member, the platform making recommendations of members of the platform that are associated with such product or content.
